Smoothness

Smoothness is a measure of the lateral pelvic movement during each stride, an indicator of stride stability.

Smoothness is a unique Motion Performance Indicator (MPI), available only with LEOMO products.

Summary

• This MPI indicates the lateral smoothness of the entire running stride. (The lower the value, the smoother the stride.)

• As lateral motion is reduced, efficiency is increased.

Why is Smoothness important?

• Smoothness reflects dynamic control of movement patterns and overall stride stability.

• A lower Smoothness score reflects an athlete’s ability to retain high coordination and synchronization of motion.

About the value of Smoothness

• Lower scores at your target speed.

• Maintain Smoothness for longer durations.

• Elite runners have shown a greater ability to maintain Smoothness values as speed increases, relative to recreational runners.

Smoothness	Level
< 30	Exceptional
30 – 40	Good
40 – 50	Average
> 50	Poor

Sensors

• Sacrum placement with LEOMO adhesive tape. 

• Attach at the Sacrum. (The largest bone at the base of the spine.)

  • See: https://en.wikipedia.org/wiki/Sacrum

• Proper placement (as seen in the image above) orients the LED in the upper left position. 

Real-time data & analysis

Smoothness can be observed in real-time.
